By using secure encryption technology to store digital currency, you only need to have a contract address to transfer the currency. The function of this wallet allows you to put the currency in your wallet when you don't use it, which is higher than the security factor in the exchange

wallet is actually used as an address protocol, because all transactions on the blockchain are recorded in the whole network. Every bitcoin transaction to an address is recorded in the whole network and cannot be tampered with. When bitcoin arrives in your wallet, everyone can see the record to prove it

unlike most traditional currencies, bitcoin is a digital currency. Therefore, the method of this kind of currency is completely different, especially when it is obtained and stored. Because bitcoin doesn't have any physical shape or form, it can't be stored anywhere technically. Instead, it is the private key used to access your public bitcoin address and sign transactions that need to be stored securely. The combination of the recipient's public key and private key makes bitcoin transaction possible

there are several different forms of bitcoin wallets, which can meet different needs, and are different in security, convenience, accessibility and so on

paper wallet

a paper wallet is essentially a document that contains a public address and a private key that can be used to receive bitcoin, allowing you to spend or transfer bitcoin stored at that address. These are usually printed in the form of QR codes so that you can quickly scan them and add the key to your software wallet for transactions

paper wallets can be generated using services such as bitaddress or bitcoinpaperwallet, allowing users to create completely random bitcoin addresses and private keys. The generated document can then be printed, some of which offer tamper proof design, and even can choose to order holographic tags and use them

the main advantage of banknote wallet is that the key will not be stored in any place in digital form, which makes it completely free from hacker attacks. It can record the malware users hit and basically any form of digital theft. However, some precautions still need to be taken when creating wallets

obviously, before generating a paper wallet, you need to make sure that no one is watching you. To eliminate the risk of any spyware monitoring activity, it is recommended to use a clean operating system running from a USB flash drive or DVD, such as Ubuntu

in addition, once the paper wallet is set up, the website code should be able to run offline, which allows you to disconnect from the Internet before actually generating the key. Finally, use a printer that is not connected to the network

in addition, it is very important to know that you are printing valuable personal information on a piece of paper. Therefore, you need to take some measures to protect that piece of paper. For example, it is suggested to put it in a sealed plastic bag to prevent water stop, moisture and general wear. Some people like to laminate it and store it in a safe, storage box or entrust a lawyer to handle it

physical bitcoin

physical bitcoin usually preloads a fixed number of BTCs, and the intention is that as long as the private key remains hidden, it cannot cost its value. This is usually achieved by implementing tamper proof seals

bitbill's first proct was like a credit card, but most of its subsequent substitutes were shaped into a round medal. Mike Cadwell, a cryptocurrency enthusiast nicknamed "casascius", created the first popular casascius physical bitcoin in 2011

the private key is hidden under the strippable hologram, and when it is removed, it leaves the tamper proof mode. In exchange, the coin lost its numerical value. Since then, there have been several new coin makers

physical bitcoin is a very convenient way to store your funds more safely, which is very useful in offline transactions. Most importantly, they have recently become a valuable collection. However, the main drawback is serious security issues

in November 2013, Mike Cadwell was asked to stop the operation of the financial crime enforcement network because his work was considered to be a money sender. The rules of the campaign were so overwhelming that he had to stop selling items containing digital bitcoin. Since BTC is still a legal gray area in many countries, these items may even be considered counterfeit by the authorities

mobile

BTC is an indispensable tool for those who actively use bitcoin every day to pay for goods or trade face-to-face in stores. It runs as a smartphone app, stores your private key and allows you to pay for things directly from your phone

in addition, some applications enable users to use their smartphone's near-field communication function, which means that they can simply click on their phone to oppose readers without having to provide any information at all

any complete bitcoin client needs to access the whole blockchain ledger, which is growing and needs several thousand megabytes of storage space. Therefore, mobile wallet uses simplified payment verification (SPV) technology. They only apply to a very small subset of the blockchain and rely on trusted nodes in the bitcoin network to ensure that they have the correct information

although bitcoin storage is a convenient mobile solution, mobile wallet is vulnerable to hackers. In addition, if someone just accesses your mobile device, you may lose control of the wallet. There are a variety of bitcoin wallet applications running on Android devices. Apple banned bitcoin wallets from the app store in February 2014, but withdrew its decision a few months later

Web wallet

Web wallet stores your private key on the server of the company providing such service. The server is always online and controlled by someone else. Different services provide different functions, some of which connect to mobile and desktop wallets to your address on the device you own

very similar to mobile wallet, e-wallet enables users to access their funds anytime, anywhere through any device connected to the Internet. But unless implemented properly, the organization that runs the site may access your private key and take full control of your money. In addition, some e-wallets operate on the basis of exchanges, and some exchanges close down and escape users' funds

Desktop wallet

Desktop wallet has been downloaded and installed on your computer, and your private key is stored on the hard disk. By definition, they are more secure than online and mobile wallets because they do not rely on third parties for data and are more difficult to steal. They are still connected to the Internet, which makes them inherently insecure. But desktop wallets are a great solution for those who trade a small amount of bitcoin from their computers

Desktop wallet has many different choices to meet different needs. Some focus on security, some focus on anonymity, etc

Hardware

Hardware wallet is a unique bitcoin wallet, which can store the user's private key in a secure hardware device. This is the safest way to store any amount of bitcoin, and there is no verifiable event that money is stolen from the hardware wallet

unlike paper wallets, paper wallets must import software at some time, and hardware wallets can be used safely and interactively. In addition, they are not affected by computer viruses, and the stored funds cannot be transmitted to output devices in clear text. In most cases, their software is open source

some hardware wallets even have screens, which adds another layer of security because they can be used to verify and display important wallet details. For example, the screen can be used to generate recovery phrases and confirm the amount and address of the payment you want to make. Therefore, as long as you invest in a real equipment with good reputation made by a reliable and competent manufacturer, your funds will be safe and reliable

bitcoin wallet and security

possible problems:

capture malware. Malware can scan your disk and find your private key. In a few seconds, all your bitcoins will disappear. Trojan can encrypt all the files on the hard disk. After that, it may find all the links to your wallet, realize how much money you have and ask for the exact amount of bitcoin to decrypt your hard drive

virtual exchange can use your money to escape. You can lose the laptop or mobile phone on which the wallet is installed

suggestions:

Bitcoin core wallet is the most complete and secure wallet on the market, and it is also the earliest bitcoin client. However, e to the huge volume of blockchain data file (blockchain) that needs to be loaded in the proct and slow startup, it will be troublesome for novices to start

bitcoin wallet

a wallet usually has multiple private keys, and many bitcoin investors also have multiple wallets. Wallets can be placed on computers and / or mobile devices, on physical storage devices, or even on paper

e-wallet - e-wallet can be downloaded software or hosted in the cloud. The former is just a format file that exists on your computer or device to facilitate transactions. Hosted (cloud based) wallets usually have a more user-friendly interface, but you will trust a third party with a private key

software Wallet - installing a wallet directly on your computer can provide you with the security of your control key. Most have relatively simple configurations and are free. The disadvantage is that they do require more maintenance in the form of backup. If your computer is stolen or damaged, and your private key is not stored elsewhere, you will lose bitcoin

Mobile Wallet - mobile wallet can be used as an application for smart phones, especially if you want to pay with bitcoin in the store or buy and sell on the road. All of the online wallets mentioned above and most of the desktop wallets have mobile versions, while others (such as Abra, airbitz and bread) are created with mobility in mind

Hardware wallets - hardware wallets are small devices that are sometimes connected to the network for bitcoin transactions. They are very secure because they are usually offline and therefore cannot be hacked. However, they may be stolen or lost along with bitcoin belonging to the stored private key. Some large investors keep their hardware wallets in secure locations, such as bank vaults. Trezor, keepkey and ledger and the case are obvious examples

paper wallets - perhaps the simplest of all wallets, these are all paper with the private key and public key of the bitcoin address printed on it. These wallets are ideal for long-term storage (obviously, away from fire and water) or as a gift of bitcoin, because they are not connected to the network, so they are more secure. However, they are more likely to be lost

with services like walletgenerator, you can easily create new addresses and print your wallet on the printer. Fold, seal, and you're done. Send some bitcoin to the address and store or distribute it safely
